Are you referring to this event? I'd hardly call that a "broke and crash during test flight". "HAV suffered a setback last November, when the parked airship broke free of its mooring mast. An onboard safety system automatically ripped open the hull in order to deflate the aircraft, thus keeping it from drifting. It has since been determined that the mishap occurred due to an incorrectly-secured locking mechanism between the airship and the mast."
